I do not yet have a specific reply from Ken
Holman, the SC34 Secretariat Manager (he's working to overcome a vast backlog
after the Seoul meeting), but I see from his weekly message about new document
postings that the Chinese comments apparently should be treated as
official:
N0728 was revised based on the late
arrival at ISO Central Secretariat of comments from the Chinese National Body
to the DIS 26300 ballot.
This means the TC needs to respond to them
as it did the other comments already received.
